Yuav ua li cas xaiv Photovoltaic Cables rau Photovoltaic Systems?

Tus nqi ntawm tooj liab tau nce tsis ntev los no, thiab tus nqi ntawm cov cables kuj tau nce.Nyob rau hauv tag nrho cov nqi ntawm photovoltaic systems, tus nqi ntawm accessories xws liphotovoltaic cablesthiab cov keyboards tau dhau ntawm cov inverters, thiab tsuas yog qis dua cov khoom siv thiab kev txhawb nqa.Thaum peb tau txais daim duab kos duab ntawm lub tuam txhab tsim thiab paub qhov tsis sib xws ntawm cov hlau hom, tuab, xim, thiab lwm yam, peb tuaj yeem pib yuav khoom nrog cov npe.Txawm li cas los xij, muaj ntau hom xov hlau, thiab ntau tus neeg siv xav tsis thoob los ntawm ntau hom xov hlau.Qhov twg zoo dua?

Thaum xaiv ib lub photovoltaic cable, peb yuav tsum xub saib ob yam: tus neeg xyuas pib thiab txheej insulating.Tsuav yog ob qhov no tsis zoo, qhov zoo ntawm cov xaim tau ua pov thawj kom ntseeg tau.

1. Tus coj

Tshem cov rwb thaiv tsev ntawm lub cable kom nthuav tawm cov tooj liab hlau sab hauv, qhov no yog tus neeg xyuas pib.Peb tuaj yeem txiav txim siab qhov zoo ntawm cov conductors los ntawm ob qhov kev xav:

01. xim

Txawm hais tias tus neeg xyuas pib txhua tus hu ua "tooj liab", lawv tsis yog 100% tooj liab ntshiab, thiab yuav muaj qee qhov impurities hauv lawv.Qhov ntau impurities muaj, qhov phem qhov conductivity ntawm tus neeg xyuas pib.Tus nqi ntawm impurities muaj nyob rau hauv tus neeg xyuas pib feem ntau yuav tshwm sim hauv cov xim.

Qhov zoo tshaj plaws tooj liab yog hu ua "liab tooj" lossis "liab tooj liab" - raws li lub npe qhia, cov xim ntawm cov tooj liab no yog xim liab, purplish, purplish-liab, tsaus liab.

Qhov loj dua qhov tooj liab, qhov sib zog ntawm cov xim thiab qhov daj ntau dua, uas yog hu ua "brass."Qee cov tooj liab yog lub teeb daj-cov ntsiab lus impurity ntawm cov tooj liab no twb siab heev.

Qee tus ntawm lawv yog cov dawb, cov no yog cov xov hlau zoo heev.Cov xov tooj hlau yog plated nrog ib txheej ntawm cov tin, qhov laj thawj tseem ceeb yog los tiv thaiv tooj liab los ntawm oxidizing los ua patina.Lub conductivity ntawm patina yog heev tsis zoo, uas ua rau kom tsis kam thiab kub dissipation.Tsis tas li ntawd, tinning tooj liab xov hlau kuj tseem tuaj yeem tiv thaiv cov roj hmab rwb thaiv tsev los ntawm kev lo, blackening thiab brittleness ntawm cov tub ntxhais, thiab txhim kho nws cov solderability.Photovoltaic DC cables yog qhov yooj yim tinned tooj liab xov hlau.

02. thickness

Thaum cov hlau txoj kab uas hla yog tib yam, lub thicker tus neeg xyuas pib, lub zog conductivity-thaum muab piv cov thickness, tsuas yog tus neeg xyuas pib yuav tsum tau muab piv, thiab lub thickness ntawm insulating txheej yuav tsum tsis txhob ntxiv.

Sim siv ntau txoj hlua ntawm cov xaim hloov tau yooj yim.Muaj tsuas yog ib tug tub ntxhais hlau nyob rau hauv ib tug cable, hu ua ib tug tub ntxhais hlau, xws li BVR-1 * 6;muaj ntau cov tub ntxhais nyob hauv ib lub cable, xws li YJV-3 * 25 + 1 * 16, Nws yog hu ua multi-core hlau;Txhua tus tub ntxhais hlau yog tsim los ntawm ntau lub xov tooj tooj liab thiab hu ua multi-strand hlau, uas yog qhov muag muag thiab haum rau cov tshuab photovoltaic.Cov xaim ib leeg tuaj yeem ua ncaj qha rau ntawm lub davhlau ya nyob twg, tab sis cov hlua ib leeg yog ib qho nyuaj thiab tsis haum rau kev teeb tsa hauv qhov chaw nrog lub voj voog me me.Rau ntau txoj hlua hlau me dua 16 square metres, nws raug nquahu kom siv cov kab txuas txuas thiab phau ntawv crimping terminal pliers.Rau ntau txoj hlua hlau loj dua 16 square meters, nws raug nquahu kom siv cov terminals tshwj xeeb rau hydraulic clamps.

2. Txheej txheej rwb thaiv tsev

Cov txheej ntawm cov roj hmab sab nraud ntawm cov hlau yog txheej rwb thaiv tsev ntawm cov hlau.Nws txoj haujlwm yog cais cov neeg siv hluav taws xob los ntawm lub ntiaj teb sab nraud, tiv thaiv lub zog hluav taws xob los ntawm kev ntws tawm sab nraud, thiab tiv thaiv cov neeg sab nraud kom tsis txhob muaj hluav taws xob poob.Feem ntau, peb txoj kev hauv qab no tuaj yeem siv los txiav txim qhov zoo ntawm cov txheej txheej insulating:

1) Kov, kov lub npoo ntawm cov txheej insulating maj mam nrog koj txhais tes.Yog hais tias qhov saum npoo yog ntxhib, nws ua pov thawj tias cov txheej txheem ntawm cov txheej txheem insulating yog qhov tsis zoo thiab ua rau muaj qhov tsis zoo xws li hluav taws xob to.Nias cov txheej insulating nrog koj cov ntiv tes, thiab yog tias nws tuaj yeem rov ua tau sai, nws ua pov thawj tias cov txheej txheej insulating muaj cov tuab tuab thiab zoo toughness.

2) Khoov, nqa ib daim hlau, khoov rov qab thiab tawm ob peb zaug, thiab tom qab ntawd muab cov hlua ncaj nraim rau kev soj ntsuam.Yog tias tsis muaj kab nyob rau saum npoo ntawm cov hlau, nws ua pov thawj tias cov hlau muaj zog dua.Yog hais tias qhov saum npoo ntawm cov hlau muaj qhov pom tseeb indentation lossis whitening loj, nws ua pov thawj tias cov hlau tsis muaj zog.faus rau hauv av tau ntev, nws yooj yim rau hnub nyoog, ua nkig, thiab yooj yim rau hluav taws xob rau yav tom ntej.

3) Hlawv.Siv lub teeb kom kub hnyiab ntawm cov hlau kom txog thaum cov hlau thaiv hluav taws kub.Tom qab ntawd tua lub teeb thiab pib lub sijhawm-yog tias cov xaim tuaj yeem raug tua tsis pub dhau 5 vib nas this, nws ua pov thawj tias cov hlau muaj cov nplaim hluav taws zoo.Txwv tsis pub, nws tau ua pov thawj tias cov nplaim hluav taws xob muaj peev xwm ntawm cov hlau tsis yog raws li tus qauv, lub Circuit Court yog overloaded los yog Circuit Court yog ib qho yooj yim ua rau hluav taws.

3. Photovoltaic System Wiring Skills

Cov kab ntawm lub tshuab hluav taws xob photovoltaic tau muab faib ua DC ib feem thiab AC ib feem.Ob qhov ntawm cov kab no yuav tsum tau muab cais tawm.DC ib feem yog txuas nrog cov khoom, thiab AC ib feem yog txuas nrog daim phiaj.Muaj ntau ntau DC cables hauv nruab nrab thiab loj fais fab chaw nres tsheb.Txhawm rau txhim kho kev saib xyuas yav tom ntej, cov xov tooj ntawm cov cables yuav tsum tau muab khi.Cais cov hlau tsis muaj zog thiab tsis muaj zog.Yog hais tias muaj cov teeb liab xov hlau, muab lawv cais kom tsis txhob cuam tshuam.Nws yog ib qho tsim nyog los npaj cov kav dej thiab cov txuas hniav, sim tsis txhob nthuav tawm cov xov hlau, thiab cov xov hlau kab rov tav thiab ntsug yuav zoo dua thaum lawv hla.Sim tsis txhob muaj cov kab sib txuas hauv cov kav dej thiab cov txuas hniav, vim kev saib xyuas tsis yooj yim.

Hauv cov tshuab hluav taws xob photovoltaic, cov phiaj xwm hauv tsev thiab cov phiaj xwm me me thiab kev lag luam, lub zog ntawm lub inverter yog qis dua 20kW, thiab qhov chaw hla ntawm ib lub cable yog qis dua 10 square.Nws raug nquahu kom sivmulti-core solar cables.Lub sijhawm no, nws tsis yooj yim rau nteg thiab yooj yim los tswj;Lub hwj chim ntawm lub converter yog nyob nruab nrab ntawm 20-60kW, thiab qhov chaw hla ntu ntawm ib lub cable yog ntau tshaj 10 square thiab tsawg dua 35 square, uas tuaj yeem xaiv raws li qhov chaw nyob;Yog hais tias lub zog ntawm lub inverter yog ntau tshaj 60 kW thiab qhov chaw hla ntawm ib lub cable yog ntau tshaj 35 square, nws raug nquahu kom xaiv ib leeg-core cables yooj yim rau kev khiav lag luam thiab pheej yig dua hauv tus nqi.
